Regulatory & Capital Matters |
Regulatory & Capital Matters | Note 11 – Regulatory & Capital Matters ​ The Bank is subject to the risk-based capital regulatory guidelines, which include the methodology for calculating the risk-weighted Bank assets, developed by the Office of the Comptroller of the Currency (the “OCC”) and the other bank regulatory agencies. In connection with the current risk-based capital regulatory guidelines, the Bank’s Board of Directors has established an internal guideline requiring the Bank to maintain a Tier 1 leverage capital ratio at or above eight percent (8%) and a total risk-based capital ratio at or above twelve percent (12%). At June 30, 2025, the Bank exceeded those thresholds. ​ At June 30, 2025, the Bank’s Tier 1 capital leverage ratio was 11.59%, an increase of 69 basis points from December 31, 2024, and is above the 8.00% Board of Directors’ guideline. The Bank’s total capital ratio was 14.99%, an increase of 117 basis points from December 31, 2024, and also above the Board of Directors’ guideline of 12.00%. ​ Bank holding companies are generally required to maintain minimum levels of capital in accordance with capital guidelines implemented by the Board of Governors of the Federal Reserve System. The general bank and holding company capital adequacy guidelines are shown in the accompanying table, as are the capital ratios of the Company and the Bank, as of June 30, 2025, and December 31, 2024. ​ The Basel III Rules are applicable to all banking organizations that are subject to minimum capital requirements, including federal and state banks and savings and loan associations, as well as to bank and savings and loan holding companies, other than “small bank holding companies,” which are generally holding companies with consolidated assets of less than $3.0 billion. A detailed discussion of the Basel III Rules is included in Part I, Item 1 of the Company’s Form 10-K for the year ended December 31, 2024, under the heading “Supervision and Regulation.” ​ At June 30, 2025, and December 31, 2024, the Company, on a consolidated basis, exceeded the minimum thresholds to be considered “well capitalized” under current regulatory defined capital ratios. ​ Capital levels and industry defined regulatory minimum required levels are as follows: ​

​ 1 Amounts are shown inclusive of a capital conservation buffer of 2.50%. 2 The prompt corrective action provisions are only applicable at the Bank level. The Bank exceeded the general minimum regulatory requirements to be considered “well capitalized.” ​ In connection with our adoption of CECL on January 1, 2020, we elected to utilize the five-year CECL transition. As of January 1, 2025, the five-year CECL transition is complete. As of June 30, 2025, the above capital measures of the Company no longer include a modified CECL transition adjustment. ​ Dividend Restrictions ​ In addition to the above requirements, banking regulations and capital guidelines generally limit the amount of dividends that may be paid by a bank without prior regulatory approval. Under these regulations, the amount of dividends that may be paid in any calendar year is limited to the current year’s profits, combined with the retained profit of the previous two years, subject to the capital requirements described above. As of June 30, 2025, the Bank had capacity to pay dividends of $118.0 million to the Company without prior regulatory approval. Pursuant to the Basel III rules, the Bank must keep a capital conservation buffer of 2.50% above the regulatory minimum capital requirements, which must consist entirely of Common Equity Tier 1 capital in order to avoid additional limitations on capital distributions and certain other payments.
